Patent GB-260440-A (GB)
Abstract: 260,440. Crawford, J. H., Helmholtz, A. W., and Farrell, D. Dec. 15, 1925. Blasting cartridges and fuzes.-Relates to blasting cartridges containing a charge of liquefied or solidified gas such as carbon dioxide. According to the invention, the cartridge comprises a rigid casing, a portion of which is of less strength than the remainder and is adapted to be ruptured by a predetermined pressure in the casing, means being combined with the cartridge for raising the temperature of the contenes above the critical temperature. In the construction shown in Fig. 1, one end of the casing 11 is closed by a plug 17, which ruptures when the liquid or solid charge is sufficiently heated by means of a resistance wire 18 surrounding the casing and in circuit with a battery 19. The casing is filled through perforations provided in the end wall 12 and adapted to be closed by needle valves 14, secured by a plug 15. Instead of the plug 17, a rupturable closure disc 43, Fig. 4, may be fitted on the end of the casing, being held in place by a screw cap 45. With such a closure, the cartridge may be used more than once, being refilled after the ruptured end disc has been replaced by a fresh one. Fig. 4 also shows a modification in the heating device, a container 46 filled with explosive being enclosed in the casing 11, together with the liquid or solid charge. The latter is gasified when the explosive is fired by heat applied electrically through the agency of the wire 18. Alternatively, the explosive may be ignited by means of an electrically-fired detonator embedded in it. In a further construction, similar to that shown in Fig. 1, an electric heating wire passes through insulated plugs in the casing, and extends through the charge from end to end, instead of surrounding the casing.

Abstract: 603,116. Brushes. STIFF, F. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 8, 1946, No. 26374/45. [Class 19] Brushes are bristled with bristles of a synthetic filament forming material each having a cross-section which is greater in one diameter than in another at right angles, the said bristles being positioned so that more than 50 per cent of the bristles have their aforesaid large dimensions substantially parallel to each other and lying in the same direction. The bristles are thereby rendered more resistant to bending in one direction than in any other and may be so positioned in tooth brushes, hair brushes, clothes brushes and other hand brushes, longhandled brushes and mechanically-operated brushes that the aforesaid direction is in that direction in which the brush most frequently moves in use. The bristles may be the shape of an ellipse, rectangle, rhombus or isoscles triangle in cross-section. Bristles of the required shape may be obtained by extrusion through a suitably shaped orifice and they may be tapered, for example, by the method described in Specifications 535,263 and 578,324, [both in Group IV]. The bristles may be glued into holes in a brush backing or inserted into a layer of heat-softened resin attached to a brush backing. Preferably, the brush is made by threading continuous filaments or bunches of filaments of correct cross-section through holes in a backing plate so as to form a series of loops on the bristle side of the plate, attaching the filaments to the plate and then cutting the loops, especially as described in Specification 588,576. The filaments are preferably made of a synthetic polyester obtained as described in Specification 578,079, [Group IV], such as polyethylene terephthalate or nylon.

Abstract: 980,155. Speech immunity circuits. STANDARD TELEPHONES & CABLES Ltd. July 5, 1963 [July 6, 1962], No. 26827/63. Heading H4R. In a multi-frequency code receiving system having a plurality of receivers equipped with speech immunity circuits, a first OR circuit is operated in response to a signal received by any, or any combination, of the receivers and operates a means to generate a delayed and lengthened pulse which is fed to coincidence gates connected in the path between the receivers and a register means. Fig. 1 shows the preferred embodiment in which a number of receivers E1 to En having speech immunity circuits have their outputs coupled to an OR gate O, or to a code checking device K, the output from which, at T, is applied to delay circuit Z1 which produces an output pulse as shown at B1, Fig. 2, the start being delayed a time tp relative to the start of pulse T. This pulse is applied to a second delay circuit Z2 which produces a pulse B2 whose finish is delayed a time tV relative to the finish of pulses T and B1. The pulse B2 is applied as one input to a set of AND gates U1, U2-Un whose other input comes via OR gates 01, 02- On from the outputs of the receivers E1, E2- En. Thus AND gates U1, U2 &c. only give an output if the signal from the receiver is maintained longer than the time tp, once the output occurs however the feedback loop from the output of the AND gate U1, U2 &c. to the input of the OR gate 01, 02 &c. ensures that the output is maintained for a minimum time tv, the delay time of Z2, which is long enough to ensure operation of the registers S1 S2-Sn.
